WIRE-N-ETTING MACHIN E.

SPECIFICATION forming part of Letters Patent No. 432,223, dated July 15,1890.

Application filed I'ebruary 12, 1889. Serial No. 299,672- (No model.)

To all whom it may concern:

Be it known that I, EDWARD SAMUEL BOND, engineer and machinist, of theCrown Engine and Machine WVorks, Lower Hurst Street East, Birmingham, inthe county of Warwick, England, and a subject of Great Britain, haveinvented certain new and useful Improvements in MachineryforManufacturing Wiredriving-gear or the means of operating the plates andpinions for twistingthewire. These plates have hitherto been operated ina Very clumsy and noisy manner, which has prevented the machines beingdriven any other than slowly, as any jerking throws the wearing partsinto more or less disorder.

Now my improved machinery is very simple, and I am therefore ablewithout risk to run the machines at, say, above twice the speed whichhas hitherto been possible. This is of course a most importantadvantage, as

netting is manufactured in a much more efj ficient manner, by reason ofthere being little.

or no vibration in the working of the'machi1 1e.'

Thus less capital is required to produce the work.

My improvements further consist in the use of a rack in each half of theplates instead of one in the one-half, thereby increasing the power ofthe pinions .for twisting stronger gages of wire and at the same timealso preventing the pinions from slipping out of gear, which is animportant failing with the present machines.

Another portion of my invention consists in the support of the plates bymeans of the stretchers being provided with flanges which receive theplates, thereby preventing them from bending in the center, also keepingthem true on their edge, and by these means allowenough of the ordinaryparts of a wire-netting machine to show the application of myimprovements thereto.

Figure 1 is a plan of both ends of the machine, the right-hand sideshowing the top plates 0 and the left-hand side showing a sectional planof the racks D, with their connections. Fig. 2 is a perspective view ofthe driving end of the machine with a portion of the frame-work brokenaway, so as to show the bevel cam-wheel A in gear with the drivingbevel-wheel F, and the mode of operating the plates 0. Fig. 3 is abroken-off elevation from the rear of the machine to show thedriving-shaft F and bevel-wheel I and the action of the internal camgroove (1?. Fig. 4 is anenlarged elevation of the center orworkingportion of the machine broken away in the middle, but showing thetwisting of the wire, one of the tubes 2 being in section. Fig. 5 is across-section through the last figure, also showing the tube broken awayto show the coil,as hereinafter explained. Fig. 6 is an enlargedsectional plan through theplates, showing the racks and pinions.

of the connecting-rod D, hereinafter described. Fig. 8 is a plan of theattachment N of the lever M to the plates 0. Fig. 9 is a side elevationof the same. Fig. 10 is a plan of the adjustable pivoted arms 13 foroperating the plates 0. Fig. 11 is a view of the ends of the plates 0,showing a modification of the method of working them.

The top and bottom plates 0, racks D, and

Fig. '7 is an elevation of the disk A and part pinions E are similar tothose in the ordinary wire-netting machine and operate upon the wire ina similar manner, as shown in Figs/I and 5i. a, one half of the plates 0slide horizontally backward and forward by means described hereinafterin the reverse direction forms the one strand of the net-tin g, theother strand 3" passing up from the spindles 3, round the roller 5,through the halves E of the bottom pinion, then up between the tubes 2,and through the halves E of the top pinions, the relative halves of thepinions being altered with regard to each other at each move of theplates (1, E being at one time opposite E, as shown at Fig. (3, andanother time opposite E, and after each change both halves are revolvedtogether by means of a.

sliding backward-and-forward mot-ion of the toothed racks D,which areoperated as hereinafter described, and which engage in the teeth 6' inthe pinions E and E By these means the wire is twisted and spread,merely forming the wire-netting, as shown by Fig. 4,. winch 1s drawnaway as formed by means of the projections 4" upon the cylinder 4, whichis mounted and revolves between the ends Y and Z of the machine.

N ow my improvements relate, first, to the operation of the plates 0, soas to obviate the use of any stops to the said plates, which I effect asfollows: I mountthe disk A upon any convenient partof themachine, butpreferably upon the brackets A and A which may be cast in one with theend Z of the machine.

The disk A is formed as a bevel-wheel, so as. to engage and receive itsmotion from the. bevel-wheel F on the main shaft F. Upon the face of thedisk the internal cam or groove a is formed, which actuates the rolleror studl h on the lever H, which, as it rises and falls,

slightly revolves the small shaft II in the bearings h and its, and bymeans of the toothed segment H engaging with the toothed seg ment K, thevertical shaft K revolves in the" bearings K and K, which are formed onthe end frame Z of the machine. The cross-arms B are fixed to the bottomand top of this shaft and are connected to the upper and lower plates Cby means of the link M and attachment N, (shown by Figs. 8 and 9,)thereby opcrating the plates 0 in the reverse direction to each other,as required.

To prevent the slightest spring or vibration occurring to throw theplates out of position, I provide the stops 71. and If to the lever H,

which may be adjusted to secure it at the ex tremes of the stroke,thereby locking the lever between the stops and the edge of the groove aoperated with a similar effect by a double eccentric or the twoeccentrics mounted uponthe shaft R, as shown in Fig. 11. To allow of themostperfect adjustment of the plates C with regard to each other, thearrangement shown by Fig. 10 isprovided, the arms B having the slots b,in which the loose pieces I) are inserted. These pieces Z) are providedwith the inclined projections N, which butt against similar inclinesformed in the side of the slots b in the arms. The set-screws b areprovided for adjusting the position of the loose pieces b, and Fig. 10shows on each side of the arm the difference in the position of the pinIf at the two extremes of adjustment. Further adjustment may be obtainedby the arrangement shown by N, Figs. 8 and 9, which is for the purposeof attaching the link M to the plates 0, the pin 01,, to which the linkMis secured, being made to move in the slot n and is afterward firmlysecured in position by the set-screws it. This arrangement is also usedfor the adjustment of the racks D. The racks D are operated at thereverse end of the machine and from the other side of the disk A bymeans of the connecting-rod D, which is connected to the vertical shaft0 and in turn to the racks D by the armsPand smaller connecting-rods Pin asimilar way to the operation of the platesC butin operating'both ofthe racks D backward and forward, as shown, instead of only one, asheretofore, it will readily be seen that as the half-pinions E altertheir relative positions with regard to each other at each stroke of theracks,andthat the endhalves e or e ateach stroke have no correspondinghalf-pinions opposite to them to allow them to revolve, they cannot whenin such position be actuated by the movement of the rack. Theindependent movement of the racks is, however, allowed by means ofcutting away the two teeth of the long half-pinion e at one end and theshort half-pinion e at the other end, so as to allow the racks D to moveindependently when these half-pinions are not able to revolve by reasonof not being in the solid part of the plate, as seen by 6 Fig. 1; but assoon as thehalf-pinion e returns opposite the next half of the pinion itforms a circle in which it can and does revolve by means of the otherhalf, which is provided with teeth and is actuated by the other rack D.I am thus enabled to work the pinions E with.

double racks, thereby obtaining increased strength for the manipulationof a thicker strand of wire; but I do not confine myself to using anyparticular number of racks in the upper or lower parts or thisparticular mode of operating the racks, in combination with the otherparts of my invention. The arms P arev provided with the slots P for thefurther adjustment of the racks.

My improvements relate, further, to the construction of the stretchersT, for connecting the ends of the machine together, which I provide withthe flange S, for the purpose of supporting the plates 0 and preventingthem from bending in the center. The stretchers 'l on each side of theplates by this means form a trough, in which the plates slide, therebyenabling me to make the machines of any desired length without fear ofthe plates bending downward in the middle, which at the same time keepsthe plates true on their edge, thereby insuring thefree and easy workingof the pinions E.

Having now particularly described and ascertained the nature of my saidinvention and in what manner the same is to be performed, I declare thatwhat I claim is 1. In combination with a pair of reciprocating plates, apair of racks attached to said plates and having their teeth facing eachother, the rack-operating devices consisting of disk A, connecting-rodD, shaft 0, arms I,

and connecting-rods P, and a set of half-pinions arranged between thesaid racks to engage them, the end half-pinions e 6 being mutilated,substantially as and for the purpose set forth.

2. In wire-netting machinery, the combination of the reciprocatingplates and wiretwisting pinions with connections between them,and theactuating devices for said plates,

consisting of a disk having an internal cam a a lever H, engagingtherewith, a shaft H operated by said lever, and the toothed segm ents Hand K, the vertical shaft K, the arms B, and the link M, connecting saidshaft and plates, substantially as set forth.

3. In combination with the wire-twisting pinions of a wire-nettingmachine and the reciprocating plates and connecting devices whereby saidpinions are operated, adj usting screws and loose blocks for regulatingthe position of said plates, substantially as set forth.

4:. In combination with the. wire-twisting pinions, reciprocatingplates, and intervening connections forming parts of a Wire-nettingmachine, a link M, pin 02, slotted piece N, and screws 11 for additionaladjustment of said plates, substantially as set forth.

In testimony that I claim the foregoing as my own I affix my name in thepresence of two witnesses.
